Xubuntu 14.04 x86_64
wine 1.8
wine-mono 4.5.6

Mono 3.2.8 packages from Ubuntu repos (I think these are the important ones):
mono-runtime: 3.2.8+dfsg-4ubuntu1.1
mono-vbnc: 3.0~pre20130627.4dcc70f-1
libmono2.0-cil: 3.2.8+dfsg-4ubuntu1.1 

Wire Gauge v3

App generates a divide by zero error if a value begins with a decimal point.  Works normally if a zero precedes the decimal point.

Steps to reproduce:
1. Start WireGauge3.exe
2. Select the Metric radio button.
3. Wire Gauge: (empty)
4. Trace Weight: 2
5. Trace Width: .2
6. Click the Wire Gauge Solve button.

I receive a "Divide by zero. Please check data!" error dialog.  If I enter "0.2" for the Trace Width, the Wire Gauge box computes "35.82".  This occurs with both mono running on Wine (wine-mono 4.5.6) and Linux mono from Ubuntu repos.  Leading zero is not required when using Wine and .Net 2 runtime (winetricks dotnet20).

Please update to recent Mono 4.2 or newer which should have this sort of errors resolved.
